The Church around the world welcomes thousands of new Catholics at the Easter vigil.

On average, more than 100,000 adults enter the Church in the United States every year. They come from every walk of life and every age group. Some arrive in the Church after many years of personal struggle, and some come at the very end of their lives. Others are moved to become Catholic because of the examples of saints, priests, religious, and exemplary laypeople and family members who give witness to Christ Jesus.

In the end, of course, they reach the same conclusion as another famous convert, Blessed Cardinal John Henry Newman: “Regarding Christianity, 10,000 difficulties do not make one doubt.”

And to be sure, many converts are encouraged in their own journeys to Catholicism by the models of more famous converts.

Movie stars, poets, novelists, musicians, philosophers, scientists and even queens were convinced in their consciences that they must become Catholic.

They were sinners (as are we all), and, as with such a diverse and interesting group, they have very different temperaments, personalities and foibles.

The dazzling variety is itself a microcosm of the many different people who enter the Church every year — and also a helpful reminder that everyone is called by Christ and that no past, however dark and troubled, makes us unwelcome to God’s loving embrace of mercy and forgiveness.
